The recommended correspondence between PostgreSQL date and time types and HDBC SqlValue
types is:

SqlLocalDate: DATE

SqlLocalTimeOfDay: TIME WITHOUT TIME ZONE

SqlZonedLocalTimeOfDay: TIME WITH TIME ZONE

SqlLocalTime: TIMESTAMP WITHOUT TIME ZONE

SqlZonedTime: TIMESTAMP WITH TIME ZONE

SqlUTCTime: TIMESTAMP WITH TIME ZONE

SqlDiffTime: INTERVAL

SqlPOSIXTime: NUMERIC

SqlEpochTime: INTEGER

SqlTimeDiff: INTERVAL

Other combinations are possible, and may even be converted automatically.
The above simply represents the types that seem the most logical correspondence,
and thus are tested by the HDBC-PostgreSQL test suite.
